e67 ecu gmpp controller kit tach hook up Hi guys I have a ls3 in my 93 rx7 with a gmpp ls3 controller kit and I am trying to hook up my tach, I am pretty sure the white wire in the bulk head is the tach but it is not working. Does anyone have the wiring diagram for the bulk head in this kit?
my cars tach is wired to the white wire in the bulk head and I have ignition with a 10k resistor tapped into it.
Thanks,
-Chance

I don't know if it makes any difference, but the instructions that came with my controller kit say that a pull-up circuit with a resistor MIGHT be necessary, but in that case, they specify 5000 ohm rather than 10000. I did not need the pull up circuit at all (Autometer tach). I just connected the white wire to the tach and it worked. I did have to configure the tach for 4 cylinder to make it read correctly.
